Sen. Edgardo Angara, on the other hand, refused to answer when asked if any member of the influential religious group, known to deliver millions of votes during elections, ever approached him to lobby for Corona.

Sen. Ferdinand Marcos Jr. also sees nothing wrong with entertaining lobbyists from either side in the impeachment trial, although no one has visited him. In the end, he said it's the senator-judges who will decide.

He also believes it's "natural" for President Aquino to talk to the INC even during the heat of the trial. On Monday, Malacanang confirmed that the President met with INC Executive Minister Eduardo Manalo.

"It is natural for the President to go and to speak and to consult about all these things and about anything," he said.

Sen. Francis Pangilinan, meanwhile, would rather not entertain lobbyists. He said no one has approached him so far.

"It would be better for us to maintain our impartiality and neutrality," he told reporters.
